A decade after her disappearance, Natalee Holloway’s family might finally get some closure as a new witness claims he saw what happened to the teenager.

The witness, Jurrien De Jong, has come forward with shocking claims that he saw the 18-year-old Holloway on the last night she was alive.

De Jong told Inside Edition that he saw suspect Joran van der Sloot carrying her body on the night she vanished.

“I saw that Joran was chasing Natalee into a small building under construction,” De Jong described. “In about five minutes he came out with Natalee in his arms, and slammed the body of Natalee on the floor, and then he made an opening in a crawl space.”

“I knew she was dead,” he concluded.

Joran van der Sloot has always been the primary suspect in the case and was even arrested twice but never charged.

The suspect, who was 17 at the time that Holloway disappeared, is currently serving time in a Peruvian prison for the murder of Stephany Flores, a college student.

He still denies any wrongdoing in connection to Holloway’s disappearance.

But why did it take De Jong 10 years to gather the nerve to come forward?

De Jong says that he didn’t go to the police at the time because he was involved in some illegal activities. But he decided to reveal what he saw after watching a TV report where van der Sloot confessed that Holloway was buried at sea.

It’s a claim that De Jong vehemently says is a lie based on what he saw that night.

Aruba’s prosecutor, Eric Olthof, says that his office is looking into De Jong’s claims and that the investigation might take about two months.

In the meantime, Holloway’s father Dave has returned to Aruba with a private detective and Inside Edition’s Lisa Guerrero to follow up on the new lead.
